Application filed September 29, 1913. Serial No. 792,305.

To all whom it mcy-cohcem:

Be it known that I,-.WILLIAM L. Konr- HAL ER," a citizen of the United States, and a residentof the township of Verdi, county of Lincoln, and State of Minnesota, have invented certain new and useful Improvements in Weed-Destroyers, of which the following is a specification.

My invention relates to improvements in machines for'destroying weeds or otheruns desirable vegetation and has ,for its object the production of a machine of this characwhich- Figure 1 is a side elevation of aweed destroying machine embodying my invention,

Fig. 2 is a top plan view thereof, andFig. 3-

is an enlarged detail section taken on substantially line: waz of Fig. 1.

The preferred form of construction as illustrated in the drawing comprises a substantially triangular supporting frame 1 which is mounted upon rear wheels 2 and front wheel 3, the machine,-when in operation, being designed to be drawn over the ground. Provided at the front end of the frame 1 is a tongue or conne ting element-4 through the medium of whi h the machine may be coupled with a traction engine 5 or I other suitable traction device equipped with rowers each of which comprises a depending I vertically disposed blade 7 rigidly secured at its upper end to said frame 1. Arranged at the lower end of each blade 7 is a spreading element 8 adapted, when the machine is in o eration, to travel just below the surface of t e ground or in the vicinity of the roots of the weeds which it is desired to destroy to effect spreading or furrowing. of the ground, the blades 7 serving simply to cleave the ground as will be readily understood.

Arranged in 'alinement with the spreading elements 8 and extending rearward there from is a lurality of perforated steam escape or ex aust pipes 9, said pipes, in thetravel beneath the ground in the furrows readily understood. The ipes 9 are connected with the lower en s of depending pipes 10 which establish communication be tween said pipes and a manifold-11 arranged at the upper side of the frame 1, said manifold being connected through a hose 12 with the boiler or source. of steam'supply' 6 of the traction element i In using the machine, the same is drawn Fig. 1 so that theblades 7 andspreading element 8 will form furrows in the ground to accommodate the pipes 9. The pipes 9 will besupplied with steam from the supply 6, the steam thus. supplied to-said pipes escaping therefrom 'jllltO the ground in the vicinity of'their passage to effect destruction of the weeds or) vegetation through scalding or scorching. The machine will be found very effective and is readily and easily operated,

While 'I have illustrated and described the preferred forn'r'of construction" for carrying my invention intolefi'ect, this iscapable of variation and modificationwithout de parting precise details" of construction set forth, bu desire to avail myself of such variations and modifications as come within; the scope of the appended claims.

Having described ters Patent is: I v

1. A machine of the class described comprising a plurality of spaced "furrowers; a plurality of parallel perforated pipes arranged in alinement with and rearward of said furrowers; and means for supplying steam, V to said pipes, v substantially as described. I

2. A machine of the class described comprising. a plurality of spaced furrowers; a plurality of horizontally disposed ara-llel perforated pipes arranged in .alinement with and rearward of said furrowers and and means for supplying steam to said pipes, substantially as described.

prising a plurality of s aced furrowers,

each of which consists o a vertically .dis-

om the spirit of theinvention. I, therefore, do not wish to be limited to themy invention what I' claim as new and desire to secure by Let- 8. A machine of the class'described com cut by the spreading elements8 as will be i over the groundin the manner shown in adapted totravel in'the furrows cutby said furrowers in the operation of the machine; 1

disposed parallel perforated pipes arranged. 5 in alinement with and rearward of said spreading element; and means for en plying steam to said described.

4:- A machine of the class described comprising. a wheeled frame; 'a plurality of transversely spaced furrowers' provided at the under side of said frame, each of said "furrowers comprising a depending vertically disposed blade adapted to cleave the ground and a spreading element at the lower end of said blade; a plurality of horizontally disposed parallel perforated pipes arranged in alinement with and rearward of said spreading element; and means for supplyin steam to said pipes, substantially as descri ed.

5. A machine of the class described comtransversely spaced furrowers provided at the under-side of said frame, each of said furrowers comprising a depending vertically disposed blade adapted to cleave the ground and a spreadmg element at the lower pipes, substantial y as end of said blade; a plurality of horizontally disposed parallel pipes arranged in almement with and extending rearwardly from said spreading element; a manifold,

furrowers so as to be adapted to travel in the. furrows cut by said furrowers in the "operation of the machine; and means for supplying a fluid weed destroyer to said pipes, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
